Abstract
An aircraft includes at least one sensor, an altitude actuator, a memory device, and an electronic controller. The at least one sensor is configured to detect altitude of the aircraft, current position of the aircraft and speed of the aircraft. The altitude actuator is configured to change the altitude of the aircraft. The memory device is configured to store predetermined terrain data of an area. The electronic controller is configured to estimate a future position of the aircraft based on a detected current position of the aircraft and a detected speed of the aircraft. The electronic controller is further configured to control the altitude actuator based on the future position, a detected altitude of the aircraft and the predetermined terrain data.
Claims14
An aircraft comprising:
- at least one sensor configured to detect altitude of the aircraft, current position of the aircraft, attitude of the aircraft and speed of the aircraft;
- an altitude actuator configured to change the altitude of the aircraft;
- a memory device configured to pre-store predetermined terrain data of an area prior to starting of a flight of the aircraft over the area;
- and
- an electronic controller configured to determine a current flight status of the aircraft from among a hovering state, a turning state and a traveling straight state based on a detected attitude of the aircraft and a detected speed of the aircraft,
- the electronic controller being further configured to estimate a future position of the aircraft in different manners according to a determined current flight status of the aircraft based on a detected current position of the aircraft, the detected attitude of the aircraft, the detected speed of the aircraft and the determined current flight status of the aircraft,
- the electronic controller being further configured to control the altitude actuator based on the future position, a detected altitude of the aircraft and the predetermined terrain data.
